Many wrong beliefs are prevalent about the causes of leucoderma. It is not caused by eating fish and drinking milk at the same time, as is generally believed because even vegetarians suffer from this disorder. Other food combinations such as pumpkin and milk, onion and milk as possible causes of leucoderma also have no basis. Leucoderma is not caused by any germs; nor is it due bad blood. It is neither infectious nor contagious. It cannot be transmitted from one person to another by physical contact. The main causes of leucoderma are excessive mental worry, chronic or acute gastric disorder, impaired hepatic function such as jaundice, worms or other parasites in the alimentary canal, ailments like typhoid which affect the gastrointestinal tract, defective perspiration mechanism and burn injuries. Often the hormone secreting glands are involved in this disorder. Heredity is also a causative factor and about 30 per cent of patients have a family history of the disorder.
